HORACE WILLIAMS, OF ST. PETERS, SOUTH AUSTRALIA, AUSTRALIA.

DIRECTION INDICATOR.

Application filed August 31, 1928, Serial No. 303,229, and in AustraliaSeptember 20, 1927.

My invention relates to an improved signalling device principally foruse in connec tion with closed motor vehicles, the object of the samebeing to provide means whereby the occupant of a closed car or othervehicle can conveniently signal his intention to turn a corner orexecute other movements if so desired.

This device consists of an arrow head or other distinguishing figurewhich is mounted upon an expanding lattice supported from a fixedportion of a car and provided with means for operating the same.

My invention will be readily understood when described by aid of theaccompanying illustrative drawings wherein Fig. 1 is a side elevation ofthe device extended to full length to display the signal.

Fig. 2 is a side elevation of the same device on larger scale but withsignal arm folded.

Fig. 3 is a plan of Fig. 2.

In each of the illustrations similar letters of reference are used todenote similar or corresponding parts wherever they occur.

In the drawings a is a fixed portion of the car as for instance a doorpillar through which a hole is drilled for the accommodation of atubular guide Z) upon the end of which there is an enlargement b and awasher may be inserted between the enlargement and the door pillar.

The opposite end of the tubular guide is screw threaded at b andsupports the clamping nut and washer c. IVithin this tubular guide Isupport a slide rod (Z, furnished at its inner end with a press buttonor stud e. The opposite end of the rod terminates with a block a whichpivotally supports the centre portion or first extension joint of anexpansible lattice the first stationary radial joint being pinned to theenlarged end or fixed block b of the tubular guide 6 by a pin or rivetg. The block 6 also supports a spring clip 6 The succeeding arms of theexpansible lattice lie parallel to each other in two rows when folded asin Figs. 2 and 3, but are extended as in Fig. 1 by the operation of theslide rod cl as will be well understood upon reference to the drawings.

The two outermost members of the lattice each support, by means ofrivets 7, plates of metal h and h preferably cut to the form of atriangle with the apex removed. When the arms of the lattice areextended as in Fig. 1 the plates h and h will appear in the form of anarrow head, but when the lattice is folded the plates h and h Will berespectively accommodated under and over the arm f as illustrated inFig. 2.

In applying my invention to practical use the device is fitted to afixed part of the car in the manner indicated and in a positionconvenient to the driver, so that when he desired to turn acorner he cangive the necessary signal by pressing the button with his hand or elbowto extend the lattice and arrow, the spindle being withdrawn when theturning evolution has been completed, and the lattice is held by theclip.

What I claim is 1. In an improved signalling device wherein expandinglattice mechanism for operating the signalling device is used, metalplates attached to the opposite sides of the outer members of thelattice, said plates being mounted so as to form an arrow head when thelattice is extended and to fold respectively under and over oppositesides of the lattice when said lattice is contracted, longitudinallyembracing the sides of said lattice.

2. In a signalling device for motor vehicles, a tubular guide passingthrough the wall of the vehicle, an enlarged outer head on said guide,an expansible lattice having its inner end attached to said head, a rodpassing through said guide, operable from the interior of the vehicleand adapted to extend said lattice, and a spring clip ext-ending fromsaid head and embracing said lattice in its contracted position to holdthe same in place.

3. In a signalling device for motor vehicles, a tubular guide passingthrough the wall of the vehicle, an enlarged outer head on said guide,an expansible lattice having its inner end attached to said head, a rodpassing through said guide, operable from the interior of the vehicleand adapted to extend said lattice, a spring clip extending from saidhead and embracing said lattice in its contracted position to hold thesame in place. and metal plates attached to the opposite sides of theouter members of said lattice, said plates being adapted to form anarrow when the lattice is extended and to embrace the latticelongitudinally on either side when said lattice is contracted.

4. In a signalling device of the expansible lattice type, a spring cliprigidly mounted on 5 the lattice support and adapted to hold saidlattice in contracted position.

5. In a signalling device of the eXpa-nsiblc lattice type a spring clipmounted on the lattice support, said clip being longer than thecontracted length of said lattice and having a bent-in end adapted tohold said lattice in contracted position.

In testimony whereof I affix my signature.
